I don't know what's happening but there seems to be a lot of glitches again. Needless to say I've spent a good number of YO $ and purchased a lot of things.
I didn't 'cash in' my next pink piggy because as I was still buying stuff. Well when I went to empty that pig I got this notice:
"Thanks for smashing all your piggy banks. Unfortunately you're all out for now"

I tried again today and it still says this.
